Solve : I have two CD-ROMs, one of which is not working?

1.	Solve : I have two CD-ROMs, one of which is not working?
Answer» I'm using Windows XP (SP2) on a AMD Athlon XP1800+ pc. I was using Samsung Combo drive. I bought an LG DVD burner recently. I have made the DVD burner as Secondary MASTER and the combo drive as Secondary SLAVE. Set the jumpers too. Both the drives are detected during booting up of PC(including BIOS). I can see both the drives with their drive letters assigned in "My Computer". The DVD burner is working fine. But when I insert a disc in the Combo drive, it says "insert a disc" and doesn't detect the disc already in it. NERO also shows both the drives, but only the master drive works. I tried changing the Combo drive to Master and the DVD burner to Slave. The master always works but the slave wont. What possibly may have gone wrong? IDE cable? OR any other XP configuration is needed?Replace the IDE cable...
